`Specification forming partof Letters Patent No. 198,639, datedDece october 3o, 1877.

To all whom it may concern.'

Be it known that I, GEORGE LUPPERT, of

` Williamsport, in the countyl of Lycoming and ings, and to thel letters ofreference marked thereon.'

The object I have in view is an improvementV upon the device for which I obtained Letters Pat-A ent dated J une 22, 18 7 5; and my invention therein consists in making both the inclined socketways in one casting, and providing a short plug-iron to jam the socket-iron into place, the plug-iron being provided with a groove in its top, and the hook-iron having a projecting end to cover the joint between the socket and plugirons, and to hold the parts together; and, further, in the combination, construction, and arrangement of the principal parts composing my bedstead-fastening, as fully hereinafter explained.

rIo enable others skilled inthe art to manufacture my improvement, Iproceed to describe the same, having reference to the drawings, in

whichj Figure l is a perspective view of the socket and plug irons with the hook-iron engaged therewith; Fig. 2, a perspective view of the socket and plug irons separated; Fig. 3, a sectional elevation of the bed-post and one of the side rails with my bedstead-fastenin g in position, and Fig. 4 a separate view of the hookiron.

Like letters denote corresponding parts' in each figure.

A is the post, and A one of the side rails, of a bedstead. The post has a vertical recess cut therein, in which are set the socket and plug irons, which recess has parallel sides and ends beveled in opposite directions, and the side rail is provided with a proper groove to receive the hook-iron, as shown in Fig. 3.

B B represent the socket and plug irons, which are made of cast-iron; but the plug-iron B may be constructed ofrwood or any other suitable material.

The socket-iron B has two sets of inclined mber a5, nm; application filed ways, a a', which engage with the lugs on the hook-iron in the usual manner. This socketiron is cast very light, and has an open center,

in which is situated a bridge-piece, b, which strengthens the iron and binds again st the central part 'of the hook-iron when in position. The outer end b of this socket-iron is beveled outwardly, as shown, to t in the end of the recess, and its inner end has an opposite beveled incline, c, which engages with the slopingend of the plug-iron. g This end, provided with the incline c,'-may be made angular, concave, or convex', or may be a plain bevel, as desired or found convenient in manufacture.

end of the recess in the post. The top of this plug-iron B has a proper groove, d, and a hole, d', is formed through the iron in the bottom of such groove, in which a screw or nail may be turned or driven to hold both irons securely in position for transportation.

(l is the hook-iron, cast in one piece, and

having the usual lugs ee and back piece f. The central bar or piece g, which connects the lugs, may be of the same thickness throughout, but is preferably thicker at the end g and has its faceinclined toward the opposite end, so as to bind more iirmlyjon the bridge-piece b. The bar g is extended beyond the lug c', to form a short projection, h, which is preferably beveled on its face. This projection, when the hook-iron is engaged with the socket-iron, binds in the groove d and covers the joint between the plug and socket iron, keeping the same firmly in place, whether or not the irons are secured by a nail or screw.

When the bedstead is manufactured, the recess is cut in each post by a suitable machine, and the socket-iron B is placed therein and moved to the upper end of the same., The plug-iron B" is "then placed in the space left at the other end of the recess, and, the two inclines c c1 coming together, the socket and plug irons are forced endwisetightlyinto place,

Anail can then be driven through the hole d.

or a screw turnedtherein, to hold. the irons in place for transportation. The hook-irons are secured-in the grooves in the sidev rails in the lIhe advantage over my former construction is in having both of the inclined sockets in one and the saine casting, so as to avoid an inaccurate fitting of the parts, which would be caused by any `displacement at the joint of the socket-irons, so as to bring the inclined sockL ets out of line and out of the same plane. a

Another advantage is in the readiness with which theplugiron B' could be replaced by a wooden plug if the saine should be lost during transportation.

I am aware that it is not original with me to construct a socket-iron having inclined ways to engage with the lugs on the hook-iron with outwardly-beveled ends and parallel sides, and

, to secure such socket-iron in a recess in abed.

post by means of a key or plug operating against one of the beveled ends of the same, the ends of the said recess being beveled inwardly away from each other; and I hereby disclaim these devices as making broadly any part of my invention.

Having thus fully described my invention, whatI claim as new therein, and desire to secure by Letters Patent, is

l. In a bedstead-fastening, the socket-iron B, having outwardly-beveled ends and carrying the inclined sockets, and the plug-iron B', provided with a grooved top, in combination with the hook-iron, having a projecting end adapted to cover the joint between the socket and plug irons, substantially as and for the purposes set forth.

2. The combination of the socket-iron B,

having parallel sides, outwardly-beveled end b', incline c, and inclined socket-ways a a', with the plug-iron B', provided with outwardlybeveled end c, incline c, and groove d in its y top, and the hook-iron, having lugs e eIV and projecting end h, all constructed and arranged substantially as described and shown.

This speciiication signed and witnessed this 17th day of October, 187 7.

GEORGE. LUPPERT.
